The modern soul accidentally fell into the fictional "Yong Dynasty" and became Shen Yan, the legitimate son of the Shen family of General Zhenbei.
The Shen family has guarded the northern border for generations, protecting the mountains and rivers of Great Yong with their iron-blooded loyalty. However, because of their outstanding achievements, they shocked the master and were deeply jealous of the current emperor Zhao Heng. After several generations of management, the men of the family have either died in battle or been framed and fallen. Now there are only a second uncle who was seriously injured and disabled in his early years, parents who have been stationed at the border all year round, and an elderly grandmother. The family seems to be prosperous, but in fact it is in turmoil.
Shen Yan has had the soul and precocious wisdom of an adult since he can remember, and is fully aware of the fatal crisis in the family's glory. He hid his sharp edge and secretly planned as a child: using modern knowledge, he quietly gathered the war orphans and established a secret force that was only loyal to himself; relying on his insight into people's hearts, he dealt with the undercurrents of the court and the old family branches, and forged a far-reaching goal. The parents at the border cleared the obstacles; even more quietly, they maintained the marriage contract they had made with Su Qingyuan, the daughter of the Su family, the richest man in the country, since childhood - it was not only a promise made by the parents of the two parents, but also a key piece on the chessboard for his future.
The whole country still remembers the Shen family's contribution to protecting the soil, and respects and sympathizes with each other, but no one knows that this heir of the Shen family is shouldering the burden of the family's survival with his young shoulders. He works step by step in the cracks of suspicion and war, vowing to change the fate of "those who make great achievements must perish", to protect his relatives, and to find his own path to peace in this troubled chess game.
